54 teams complete Iditarod Trail dog sled race

When the small town of Nome, Alaska was ravaged by an outbreak of diphtheria in the winter of 1925, teams of sled dogs delivered the nearest supply of a life-saving serum from Anchorage, nearly 1,000 miles away.

Since 1973, the life-saving voyage is commemorated each year with the Iditarod Trail Dog Sled Race – a competitive trek from Anchorage to Nome.
